[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1 As shown, the utility model discloses a door controller test bench, including a test bench body 20, on which are provided: an external lock switch 1, which is used to connect to the external operation interface signal of the door controller; a 98% switch 2, which is used to connect to the 98% switch interface signal of the door controller; a 100% switch 3, which is used to connect to the 100% switch interface signal of the door controller; an isolation lock switch 4, which is used to connect to the isolation lock interface signal of the door controller; an indicator light 5, which is connected to the door status interface signal of the door controller; a buzzer 6, which is used to connect to the buzzer 6 interface signal of the door controller; a door opening switch 10, which is connected to the external operation interface signal of the door controller; a door closing switch 11, which is connected to the external operation interface signal of the door controller; a pressure switch 12, which is connected to the pressure reducing valve 9; and an internal lock switch 14, which is connected to the internal emergency interface signal of the door controller.

[0041] The utility model simulates the corresponding structure of an actual bus through structures such as an outer lock switch 1, a 98% switch 2, a 100% switch 3, an isolation lock switch 4, an indicator light 5, a buzzer 6, a door opening switch 10, a door closing switch 11, a pressure switch 12 and an inner lock switch 14 on a test bench body 20. In this way, by connecting the above-mentioned structure of the test bench body 20 with the corresponding interface of the door controller, the function of the door controller interface can be tested, so that the door controller does not need to be repaired with the actual vehicle when entering the warehouse, and the interface fault detection can be completed, that is, the fault detection process of the door controller interface is simplified, making the fault detection of the door controller interface easier.

[0042] The test bench body 20 is provided with two sets of identical external lock switches 1, 98% switch 2, 100% switch 3, isolation lock switch 4, indicator light 5, buzzer 6, door opening switch 10, door closing switch 11, pressure switch 12 and internal lock switch 14, which correspond to the left and right doors of the real bus structure, so that the utility model can simultaneously perform fault detection on the left and right door functions.

[0043] It should be noted that the various devices on the test bench body 20 in the present invention simulate various action mechanisms of the plug door. After the plug door controller is connected to the test bench body 20, the signal is transmitted to the plug door controller through the door opening and closing switch. Under normal circumstances, the execution of each mechanism and the plug door controller signal will be executed in sequence. When a certain link is no longer executed or repeatedly executed, it can be determined that there is a fault in the plug door controller controlling the functional part.

[0044] The pressure reducing valve 9 is used to connect to the speed interface signal of the door controller, and the pressure reducing valve 9 is connected to the door switch cylinder 19; and / or, the door controller test bench also includes an electric lock switch 15, and the electric lock switch 15 is connected to the electric key interface signal of the door controller.

[0045] The door controller test bench also includes an anti-squeezing switch 13, which is used to connect with the anti-squeezing interface signal of the door controller; the door controller test bench also includes a foot pedal, which is used to connect with the foot pedal interface signal of the door controller; and a foot pedal indicator light 18, which is connected with the foot pedal signal. When the foot pedal locking signal is sent through the software, the foot pedal indicator light 18 is on.

[0046] The door controller test bench also includes a 98% indicator light 16, which is connected to the pedal signal; a 100% indicator light 17, which is connected to the pedal signal; and a power supply interface is also provided on the door controller test bench, which is respectively connected to the door controller's left opening interface, right opening interface, door closing interface, address interface, and overvoltage interface. The power supply interface can be a 37-pin plug.

[0047] The door controller test bench also includes a first communication interface, which is connected to the second communication interface of the door controller; a controller, which is connected to the external lock switch 1, the isolation lock switch 4, the door opening valve 7, the door closing valve 8, and the pressure reducing valve 9.

[0048] The door controller test bench is also provided with an opening valve 7, which is used to connect the door opening valve 7 interface signal of the door controller; an opening solenoid valve, which is respectively connected to the door opening valve 7 and the door switching cylinder 19; a closing valve 8, which is used to connect the door closing valve 8 interface signal of the door controller; a closing solenoid valve, which is respectively connected to the door closing valve 8 and the door switching cylinder 19.

[0049] The door controller test bench of the utility model can be used for troubleshooting of door controllers, and can be particularly used for troubleshooting of TX-2 electric-controlled pneumatic plug door controllers.

[0050] Among them, the pressure reducing valve 9 in the utility model is connected to the door opening and closing cylinder 19, so that the utility model can simulate the actual rodless cylinder on the bus through a small cylinder by means of pressure reduction. The specific simulation method is: the 600Kpa pressure of the door opening and closing cylinder 19 is reduced to 240Kpa by the pressure reducing valve 9. This process takes 2s, which just simulates the door closing time of about 2s required by the actual bus, thereby completing the transition of the foot pedal from the open door state to the closed door state. In addition, by adjusting the pressure reducing time of the pressure reducing valve 9, the fault alarm function of the door controller can be tested. The door opening and closing cylinder 19 is a rodless cylinder, which moves to the left to open the door and moves to the right to close the door; at the same time, because the actual door is opened and closed by the cylinder, the switching action of the door opening and closing cylinder 19 represents the opening and closing of the door.

[0051] In the utility model, the outer lock switch 1, the inner lock switch 14, the pressure switch 12, the anti-extrusion switch 13, the isolating lock switch 4, the electric lock switch 15, the door opening switch 10, the door closing switch 11 and other structures are all connected to the corresponding structures on the actual bus (here, it is not the corresponding structure on the actual bus, which can be understood as the structure removed from the bus or newly purchased). Therefore, the above-mentioned structure in the utility model can realize the functional simulation of the outer lock switch 1, the inner lock switch 14, the pressure switch 12, the anti-extrusion switch 13, the isolating lock switch 4, the electric lock switch 15, the door opening switch 10, the door closing switch 11 and other structures on the actual bus.

[0052] like Figure 2 As shown, the working process of the door controller test bench in the utility model is as follows:

[0053] Power-on initialization state: the test bench is powered on, the door opening valve 7 is closed, the door closing valve 8 is opened, the door opening solenoid valve is disconnected, the door opening and closing cylinder 19 moves to the right, the door closing solenoid valve is closed, and the buzzer 6 sounds three times. At this time, the bus structure simulated by the door controller test bench is in the door closing state, the 98% indicator light 16 is on, and the 100% indicator light 17 is on (for the sake of simplicity of description, the "bus structure simulated by the door controller test bench" will be referred to as the "bus structure" below).

[0054] Among them, power-on initialization means that after the test bench body 20 is powered and gas is supplied, the door automatically performs a test action to confirm that each structure on the test bench body 20 is working normally. The two actions of opening the door solenoid valve and closing the door solenoid valve in the above content can be performed manually by the operator. And during the power-on initialization state, the isolation lock needs to be closed so that the isolation lock is in a closed state.

[0055] After the door closing action starts, the state of the isolation lock is detected first. If the isolation lock is closed, that is, the isolation lock is in the isolation position, the coach structure remains in the closed state;

[0056] If the isolation lock is disconnected, that is, the isolation lock is in the non-isolation position, at this time, if the driving speed of the bus structure is ≧5km / h, the controller controls the opening and closing of the bus structure; if the driving speed of the bus structure is less than 5km / h, the operator manually controls the opening and closing of the bus structure.

[0057] When the travel speed of the bus structure is ≧5km / h, if the controller recognizes the centralized door closing signal (the centralized door closing signal is brought by the inner lock switch 14 or the outer lock switch 1), that is, the centralized door closing state is latched, it means that the door has completed the closing action. At this time, the bus structure is in the closed state.

[0058] When the travel speed of the bus structure is ≧5km / h, if the controller does not recognize the door closing signal or recognizes the centralized control door opening signal, it means that a door is not closed. At this time, the buzzer 6 sounds 3 times, each sound lasts for 0.3s, and the interval between each adjacent sound is 0.7s, and the indicator light 5 is on, and the door is reopened: the door opening valve 8 and the door closing solenoid valve are disconnected, the door opening valve 7 and the door opening solenoid valve are opened, and the door opening cylinder 19 moves to the left, driving the door to open. When the door is fully opened, that is, in the open state, the pedal position indicator light 5 is on, and the state of the isolation lock is re-detected.

[0059] If the isolation lock is closed, that is, the isolation lock is in the isolation position, the door opening valve 7 and the door opening solenoid valve are disconnected, the door closing valve 8 and the door closing solenoid valve are opened, and the door opening and closing cylinder 19 moves to the right, driving the bus structure to close the door until the controller recognizes the 98% door closing signal and continues to close the door. When the controller recognizes the door closing signal, that is, the 100% door closing signal, the indicator light 5 goes out. If the controller does not recognize the door closing signal, that is, the 100% door closing signal, the indicator light 5 lights up. Subsequently, when the controller recognizes the door closing signal, that is, the 100% door closing signal, if the controller receives the pedal in place signal, the pedal position indicator light 5 goes out, which means that the door closing action is completed and the bus structure door is completely closed. When the controller recognizes the door closing signal, that is, the 100% door closing signal, if the controller does not receive the pedal in place signal, the pedal position indicator light 5 lights up.

[0060] If the isolation lock is disconnected, that is, the isolation lock is in the non-isolation position, at this time, if the driving speed of the bus structure is ≧5km / h, the controller controls the opening and closing of the bus structure; if the driving speed of the bus structure is less than 5km / h, the operator manually controls the opening and closing of the bus structure.

[0061] When the speed of the bus structure is ≧5km / h, the buzzer 6 sounds 3 times, each lasting 0.3s, with an interval of 0.7s between each adjacent sound, the door opening valve 7 and the door opening solenoid valve are disconnected, the door closing valve 8 and the door closing solenoid valve are opened, and the door opening and closing cylinder 19 moves to the right. If the controller detects an anti-squeezing signal, the door opening valve 7 and the door opening solenoid valve are opened, and the door opening and closing cylinder 19 moves to the left. After 5s, the door opening valve 7 and the door opening solenoid valve are disconnected, and the door opening and closing cylinder 19 stops moving to the left. The door closing valve 8 and the door closing solenoid valve are opened, and the door opening and closing cylinder 19 moves to the right, driving the bus structure to close the door until the controller recognizes a 98% door closing signal and continues to close the door. When the controller recognizes the door closing signal, i.e., the 100% door closing signal, the indicator light 5 goes out. If the controller does not recognize the door closing signal, i.e., the 100% door closing signal, the indicator light 5 is on. Then, when the controller recognizes the door fully closed signal, i.e., the 100% door closed signal, if the controller receives the pedal fully closed signal, the pedal position indicator light 5 goes out, which means that the door closing action is completed and the coach door is fully closed. When the controller recognizes the door fully closed signal, i.e., the 100% door closed signal, if the controller does not receive the pedal fully closed signal, the pedal position indicator light 5 goes on.

[0062] When the speed of the bus structure is less than 5km / h, and the controller does not detect the centralized control door closing signal, the door is reopened, and then the isolation lock state detection and vehicle speed detection are performed until the controller detects the centralized control door closing signal. When the controller detects the centralized control door closing signal, the centralized control door closing state is latched, the buzzer 6 sounds 3 times, each sound lasts 0.3s, and the interval between each adjacent sound is 0.7s. The door opening valve 7 and the door opening solenoid valve are closed, the door closing valve 8 and the door closing solenoid valve are opened, and the door opening cylinder 19 moves to the right to drive the door to close. When the controller detects the anti-squeezing signal, the door opening valve 7 and the door opening solenoid valve are opened, and the door opening cylinder 19 moves to the left to drive the bus structure to open the door, and the door closing valve 8 and the door closing solenoid valve are closed for 10s. The door closing valve 8 and the door closing solenoid valve are opened again, and the door opening cylinder 19 moves to the right to drive the door to close. If the controller still detects the anti-squeezing signal, the door is opened for 10s and closed until the controller cannot detect the anti-squeezing signal. When the controller does not detect the anti-squeezing signal, the door continues to close until the controller recognizes 98% of the door closing signal, and then continues to close the door. When the controller recognizes the door closing signal, i.e., 100% of the door closing signal, the indicator light 5 goes out. If the controller does not recognize the door closing signal, i.e., 100% of the door closing signal, the indicator light 5 lights up. Subsequently, when the controller recognizes the door closing signal, i.e., 100% of the door closing signal, if the controller receives the pedal in place signal, the pedal position indicator light 5 goes out, which means that the door closing action is completed and the bus structure door is completely closed. When the controller recognizes the door closing signal, i.e., 100% of the door closing signal, if the controller does not receive the pedal in place signal, the pedal position indicator light 5 lights up.

[0063] It should be noted that the utility model simulates the effect of the rodless cylinder on an actual bus through the cooperation of a small cylinder and a pressure reducing valve 9 (the stroke of the small cylinder is 250 mm): the pressure of 600 Kpa required by the rodless cylinder of the actual bus is reduced to 240 Kpa through the pressure reducing valve 9. This process takes 2 seconds, thereby realizing the simulation of the process of switching from an open door state to a closed door state of the actual bus, and avoiding the use of a 2.5 m long rodless cylinder in an actual bus, which would result in a greater safety hazard in the test.

[0064] Among them, the signals of the speed of the coach structure <5km / h or the speed of the coach structure ≧5km / h are sent to the controller by the torsion switch on the test bench body 20 to control the intermediate relay to realize the automatic door opening or closing action. The external operation signal and the internal operation signal collectively control the door opening signal provided by the door controller. When the door controller recognizes the door closing signal, if the door is not closed, it means that the door controller recognizes that there is a fault or the anti-extrusion switch 13 is working. If the controller does not receive the pedal in place signal and the pedal position indicator light 5 is on, it means that a fault has occurred and the subsequent experimental operation is performed.

[0065] The door controller test bench in the utility model can be designed as a suitcase, which is connected to the door controller to test various functions of the door controller, so that the door controller can be fully tested on site without the need to perform fault detection on the actual vehicle when entering the warehouse, thus simplifying the steps of door controller fault detection, and determining whether the logical function or physical function of the door controller is obstructed, making the maintenance of the door controller easier.

[0066] For example, the door controller test bench in the utility model can effectively troubleshoot faults such as door opening failure, door closing failure, abnormal door opening, anti-squeezing function failure, isolation function failure, and centralized control function failure of the door controller.

[0067] In summary, the present invention tests the following functions of the door controller:

[0068] 1. Startup / operation current test: by measuring the voltage output of each function and the overall gate controller working current, the aging degree of the power output device is calculated. When it reaches 60%, it prompts to update the corresponding electronic devices.

[0069] 2. Door opening function test: During the door opening process, test the time it takes for the door controller to control the door to close if there are no component failures.

[0070] 3. Fault test item by item: After opening and closing the door external operation or electric key operation (both items must be tested separately), simulated faults occur in each component one by one, and the door should stop moving. (When 98% closed door, 100% closed door, anti-squeeze switch, internal emergency, door opening valve 7, and door closing valve 8 fail, the protection function must be turned on).

[0071] 4. Logical function test: Test the electric key, external operation logic reversal function, and when the door is closed, the door controller should execute the door opening action, and when the door is open, it should execute the door closing action.

[0072] 5. Lonworks bus function test: The door controller should send correct information to the system.

[0073] 6. Centralized control function test: The system should correctly execute the electrical instructions of the centralized control of the train doors.

[0074] The utility model uses electrical, electronic, compressed air systems, computers, and single-chip computer programs to establish a door controller test and detection platform. Through electronic and electrical components, the failure of any one or more components in the system is simulated, and the door controller should perform corresponding protection actions. After the failure is eliminated, the car door should be closed and opened normally.

[0075] The utility model realizes the single fault and multiple fault simulation of the complex functions of the gate control system, thus realizing the single-step technical test and test function of the gate controller logic control function. Through this technology, the function test of the gate controller logic and photoelectric coupling, MOS tube input and output single electronic devices can be realized. At the same time, the test bench integrates the simulation of the gate controller Lonworks bus input / output function.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
